pump not keeping prime

Jun 12, 2012
I have a 16000 gal fiberglass pool with sand filter, about 10 years old. I used to be able to use a timer for turning the pump on and off but the pump needs to be primed manually now. It has some air in the basket before the pump while running, but no air in the return lines. Suggestions?

check the gasket on the basket cover,, pump drain plugs,,, lots of good people on here that have mountains of knowledge,, they'll be along shortly...

from looking at my specific pump, it takes a 1/4" drain plug. My local pool store can get me a hayward 1/4" plug... that's not my pump manufacturer. Is it likely to work (is a drain plug a fairly universally interchangable part)?
